France has been moving this way for some time - I hope they really do it. I used to live in Lyon and there was a big problem with women who had been trafficked from Eastern Europe. There was very little attempt made to hide the activities - the women were identifiable because they all wore long black coats. There were turf wars and the whole thing was of course controlled by organised criminals. IIRC the same schema existed in Paris too.
I used to work near the area concerned and it was awful seeing these women.
I hope this really happens.
